Male cannabis plants produce very few cannabinoids, which means growers potentially have to scrap 50% of their crop. For this reason, we have developed feminized seeds. But just what are feminized seeds, and where do they come from? The answer is a remarkable feat of genetics and horticulture. "Hermie" cannabis plants can look like normal female plants at first glance, but they produce pollen that causes seedy buds. Hermies are to be avoided!" Do feminized plants produce seeds? Yes. Continue reading this article to know the why, what, and how of growing feminized plants.
Feminized Cannabis Seeds Explained
L ike many living things, cannabis plants come in two sexes, male and female, which blend their genetics through pollination to produce seeds. These seeds then, have about a 50% chance of inheriting the sex of either parent. However, male cannabis plants produce very few cannabinoids, which faces many growers with the prospect of scrapping about 50% of their crop (unless, perhaps, they’re making their own rope). For this reason, we have developed feminized seeds. But just what are feminized seeds, and where do they come from? The answer is a remarkable feat of genetics and horticulture.
What are Feminized Seeds?
Feminized seeds are cannabis seeds genetically guaranteed to grow into a female plant. Female plants produce far more THC and CBD than their male counterparts, but once a female plant is fertilized, resources and energy are diverted from growing rich, sticky flowers, to growing a healthy crop of seeds instead. Those seeds are, of course, wonderful and necessary, but they may inherit the gender of either parent, and, as we have seen, males are nearly useless for harvesting cannabinoids.

When growing for cannabinoid production, pumping water, fertilizer, and time into your plants only to find half are male can be frustrating to say the least. A single male plant can pollinate an entire grow room, leaving whole crops producing seeds instead of flowers. Additionally, inspecting your plants for male attributes and removing them from the grow room takes time and attention that could otherwise go to treating female plants. For this reason, we have learned how to breed feminized seeds – seeds that we know will grow up to be female, and produce lush flowers rich with therapeutic cannabinoids.
How Feminized Seeds Are Made
Female seeds must come from two female parents, which on the surface sounds impossible. But under extreme circumstances, female cannabis plants can produce their own pollen. So the first step toward feminized seeds is inducing pollen production on a female plant.
The primary method is to douse the flowering sites with a solution of colloidal silver, or less commonly, with gibberellic acid, for about two weeks once the flowering stage has begun.
These chemicals will suppress the hormone ethylene, which causes the plant to produce male characteristics instead, including pollen sacs. And since the plant is still genetically female, the pollen within will carry 99% female genetics (a small margin of mutation is unavoidable). This pollen can then be harvested and applied to a flowering female plant to produce seeds with purely female genetics.
The less common, but more natural, method is called “rodelization,” often favored by organic growers. Near the end of a cannabis plant’s life cycle, unfertilized females will begin to express male pollen production as a final effort to continue their genetic line. This usually occurs after the prescribed time frame for harvesting, but not always. In fact, many growers keep a sharp eye out for these “nanners” – the banana-shaped growths that protrude from flowers – because they are capable of fertilizing other plants as well, thus halting flower production.
There is a debate among growers about the viability of this method because some believe hermaphroditic plants primarily produce hermaphroditic offspring. Others insist that offspring are not more inclined to be hermaphrodites, but rather may be more easily induced to be hermaphrodites, and that hermaphroditism has less to do with genetics than external stressors (high heat, nutrient lock, physical damage, etc.). Regardless, most growers agree that rodelization is less effective and carries a higher risk of accidental pollination. For this reason, it is more often used by more experienced or meticulous growers who want to maintain the organic integrity of the plant.
Feminized seeds have become the industry standard, especially for home growers who do not have the space or resources to scrap half of a crop that turns out to be male. Many sites now default to offering feminized seeds, some growers have undoubtedly planted them without fully understanding the science behind them. And one thing that makes these seeds so popular is that you can, you can grow them without knowing what they are or how they exist, and they will still deliver a lush, low-maintenance cannabis plant.

Do Feminized Cannabis Seeds Make Hermies?
What Are Feminized Cannabis Seeds? These seeds all grow up to be female plants. That means every plant produces buds. With “regular” or unfeminized seeds, about half the plants will turn out to be male, which don’t produce buds. They can also pollinate your female plants (causing seedy buds). Therefore most growers will remove male plants from the grow room as soon as they’re identified. Learn more about male vs female plants. Feminized seeds let you plan your grow more effectively because you don’t have to throw half the plants away once they start flowering.
Every plant grown from feminized seeds will produce the buds we know and love. This plant was grown from feminized Swiss Cheese seeds.
What Are Hermies? “Hermie” is short for “hermaphrodite.” Hermie cannabis plants usually look like normal female plants for the most part, but they also grow some male parts that produce pollen. This causes seedy buds just like pollen from male plants. Hermies are to be avoided! Read the full tutorial on hermies.
It’s no good if your “female” plants start growing male flowers or parts of male flowers. That can cause seedy buds just like a male plant!
This bud got completely seeded due to a hermie in the grow space. Notice the lumpy round bits. Those are seeds forming.
What’s the matter with a few seeds?
Cannabis growers are trying to grow sinsemilla (seedless buds). A few seeds won’t hurt anything. But if you have very seedy buds, it significantly lowers your yields because plants are putting all their energy into making seeds. The buds also tend to be less potent if they are full of seeds. Seeds are not the end of the world, but it’s good to avoid if possible.
“Sinsemilla” means “no seeds.” Sinsemilla is the highest quality and most potent of all buds
Since most growers are trying to grow sinsemilla, having only 100% female plants in the flowering grow room is crucial to prevent pollination.
Feminized cannabis seeds can be a blessing for small-scale growers. While male plants produce pollen sacs, feminized seeds ensure all your plants will end up being bud-bearing females (instead of growing half male and half female plants like with regular seeds).
If you don’t have room for extra plants, feminized seeds can make planning your grow a lot easier!
Good feminized seeds should produce only 100% female plants, with no hermies or male plants. So starting with feminized cannabis seeds lets you make the most efficient use of your grow space. You don’t have to worry about identifying male plants and throwing them away before they pollinate your female plants. With good feminized seeds, you know that if you’re growing 10 plants, all 10 of them will make buds, and that makes it easier to plan out your grow ahead of time.
With all these bonuses, why would any small-scale grower use any other type of seeds?
Pros of Feminized Cannabis Seeds
All plants produce buds
You don’t have to throw away half your plants after nurturing them for weeks
You don’t have to worry about your buds getting pollinated, causing seedy buds, reduced bud quality and lower yields
But is there a dark side to feminized cannabis seeds?
One of the biggest worries growers have about feminized seeds is that they will produce hermies instead of 100% female plants as advertised.
This hermie is growing both male and female flowers. Can this be caused by feminized seeds?
Unfortunately, hermies can be a lot easier to miss than a male plant since it may just be a small part of the plant that’s affected. A male plant makes itself known at the beginning of the flowering stage, but a hermie plant may grow only buds except for just one or two tiny pollen sacs. A few yellow hermie bananas hidden in the buds can also produce pollen. Any type of male flower part that grows in your garden can add seeds to your buds, and hermies are some of the worst offenders.
This grower didn’t notice that the buds had been seeded until harvest. As he was trimming, he noticed seeds popping out. Since there were no male plants, chances are this was caused by an unnoticed hermie somewhere in the grow space.
Is it True that Feminized Seeds Sometimes Cause Hermies? Yes!
Many growers believe that feminized seeds can cause hermies, and there is some truth to that. In order to create a feminized seed, one of the parent female plants had to be forced in some way to produce pollen.
That pollen is used to pollinate another female plant, and the offspring of those two plants will all be female since both of the parents were female. That’s how you get feminized cannabis seeds. But that also means every time you have a feminized seed, that seed had a plant that produced male flowers in its recent genetic history.
There are different ways to feminize seeds, but only some methods produce seeds that turn hermie on you.
It’s important to understand that hermies can happen a couple of different ways. And the different types of hermies affect what genes are being passed on to the seeds.

What Causes Hermies?
Hermies can be caused by many things, including…
bad genetics – the plant comes from a line of plants that naturally create hermies for no reason, even in good growing conditions
high stress – high temperatures, light leaks, inconsistent light schedules, as well as other types of major stress can cause a healthy plant to hermie, though some plants/strains are more susceptible than others
letting buds over-mature – this is also known as “rodelization;” basically when the plant’s buds have gone past maturity without being pollinated (if the grower waits way too long to harvest), a female plant may make male pollen within its buds as a last ditch effort to pollinate itself and make seeds for the next generation
chemical stimulation – by exposing a female plant to certain substances like colloidal silver or gibberellic acid during the early parts of the flowering stage, you can force any female plant to create pollen. This is how seedbanks get female pollen to produce feminized seeds.
Seeds created from “female” pollen will turn out being female (or at least as female as the parents).

Another type of hermie: a yellow “banana” can appear in your buds and make pollen. This male flower part would normally be inside a pollen sac. When it’s in the open like this, it becomes a little pollen generator.
Feminized seeds are susceptible to becoming hermies themselves when exposed to the same conditions as their female “father” who produced the pollen. But since any plant can be chemically induced to produce pollen, it doesn’t mean that the ability to hermie in a natural environment is passed on to the seeds.
So only some feminized seeds come from parents with bad genetics, and that’s what’s the grower cares about most.
The bagseed gamble… When you find seeds in your buds, that usually means that the buds were pollinated by accident. Seeds that were accidentally created are suspect. It could be that a stray male plant caused them, which means there were no hermies and you will get about half male and half female plants. But accidental seeds could also be the result of herming by an indiscriminate grower, and that means you have feminized seeds, sort of. Some of them may produce pollen on you just like their parents. Growing with bagseed is a big gamble… you never know what you’re going to get.
Are your cannabis bagseeds viable? Viable, good seeds usually appear either dark and striped or solid gray/beige.
If a seed is pure white it usually means it’s underdeveloped and won’t sprout. But it can sometimes be hard to tell. In the end, if a seed sprouts and grows it’s a viable seed! I’ve had very pale, flimsy seeds sprout into gorgeous fast-growing plants, so if you’re not sure the best thing to do is try to germinate it!
Seed Banks & Breeders
Commercial breeders and seed banks use chemical stimulation to create feminized seeds. What that means is they put specific compounds on developing female plants to force them to produce pollen. You can actually do this yourself at home.
This technique works on nearly any female plant, including plants that would never hermie naturally. So it can be used to take two plants with great genetics to produce female seeds. But the same process will also work incredibly well on plants that do hermie easily all on their own. That means it’s up to the breeder to test and make sure that they have a solid plant with unbeatable genetics before using the feminization technique.
The pollen that results from chemical stimulation is used to pollinate another female plant and make feminized seeds. If the parent plants would never hermie without chemical stimulation, then you have created feminized seeds that won’t ever make pollen in your grow room.
But if one of the parent plants was chosen because it does hermie easily, you’ll end up with seeds that likely will herm. The breeder might not have done any testing on the parents or the resulting offspring to even know.
Without testing, a breeder can’t tell whether they’ve created quality feminized seeds
Choosing the Right Cannabis Breeder
Unfortunately, some cannabis seed breeders are more trustworthy than others. The great ones have created stabilized strains that have been bred over several generations to produce a consistent product without any problems with plant sex.
Less scrupulous breeders might breed two random female plants together and sell the resulting seeds as a new strain without any testing. In this second case, you don’t know what to expect, and neither does the breeder.
If the breeder hasn’t tested their strains extensively in many situations, they won’t know whether their seeds tend to hermie or not. If they have carelessly bred plants that have a tendency to herm, then it’s really likely that at least some of the resulting seeds will have the same problem.
Breeder choice is important!
I have to admit I may be biased towards feminized seeds. I’ve grown almost exclusively with feminized seeds over the last decade. It has made my life so much easier! I only purchase seeds from breeders that I trust and all the resulting seeds have been bud-bearing females. I haven’t had any real problems with hermies.
On the flip side, I’ve heard of growers buying feminized seeds from untrustworthy breeders and having a big portion of their seeds turn male or become hermies even in perfect growing conditions. So there is truth to the fact that you can run into hermie problems with feminized seeds.
Yet there are good and bad breeders out there, and with good breeders, you have a very low chance of running into cannabis sex problems.
So if you do choose to purchase feminized seeds (or any seeds really), please make sure you get them from a trusted breeder!
Conclusion: Feminized seeds from a trustworthy breeder have a low chance of producing hermies, but the odds are much worse with feminized seeds from an untrustworthy source
The truth is it takes a hermie of some sort to create feminized seeds. That means that you always run the risk of running into hermies when growing feminized seeds… yet that is true for non-feminized cannabis seeds, too! Lots of regular seeds produce hermies.
What’s most important, whether you get feminized seeds or not, is to get your seeds from a breeder who has a reputation for producing quality genetics. That is the best thing you can do for any strain to ensure a smooth grow. With a great breeder, you have a very low risk of running into any sex or gender problems.
I personally prefer feminized seeds, and that’s the only type of seed I grow. It makes it easier for me in my limited grow space. I haven’t run into any significant problems with hermies, so I’m satisfied with growing only bud-bearing plants.
Yet a lot of growers grow with regular seeds because they’re easier to breed and produce at home. Many growers have created a system for weeding out male plants that is more convenient for them than using feminized seeds.
In the end, when it comes to feminized cannabis seeds you need to decide whether the small chance for hermies is worth the convenience of all-female plants. It’s up to you to figure out what’s best for your needs!
Do Feminized Plants Produce Seeds: Question Answered
Any cannabis user who has enjoyed and savored a cannabis joint owed this feeling to the fruits of the cannabis, more specifically to the female species. The reason behind is that only the female cannabis produces the cannabinoid-rich flowers that are responsible for the flavors and effects that users look for. A lot of cannabis growers are using feminized seeds but some people are curious, do feminized plants produce seeds?
These feminized seeds are cannabis seeds that only carry female genetics and can be relied on to produce only female plants. Cannabis growers apply creative techniques to seed feminization to ensure female genetics in seeds partnered with a nearly 100% success rate. Here we give you the overall information you might need to know about feminized cannabis plants.
What are Feminized Cannabis Seeds?
Feminized cannabis seeds are produced in a way to ensure that all the resulting plants will be female. The difference they have with regular cannabis seeds is that the regular seeds will produce half male and half female plants.
Although having a male plant can be considered an asset to any breeding program, the downside is having to watch over and throw away half the plants. This can be a waste of time and space for growers who needs to have a continuous supply of cannabis bud.
Do Feminized Plants Produce Seeds?
If you’re a novice in the cannabis industry and you’re wondering do feminized plants produce seeds, the answer to curiosity is that yes. It will produce seeds and the seeds will become feminized as well.
A lot of cannabis growers invest in growing feminized plants because of the sure return of the feminized seeds. These seeds are going to give female plants that in turn will produce buds and the cycle will repeat itself automatically.
How to Feminize Cannabis Seeds
There are two methods to feminize seeds: naturally or by applying a chemical substance that forces a female plant to pollinate. In essence, a severely distressed female cannabis plant will naturally become a hermaphrodite and it will produce pollen sacs in order to self-pollinate.
This is actually a survival mechanism built into all female cannabis plants but this can only be triggered when the future of the plant’s lineage is compromised. Having a hermaphrodite can cause a disastrous breeding situation as it can pollinate female plants that are meant to be harvested which will, in turn, cause the buds to stop developing and to produce seeds.
Using a colloidal silver to a female plant is the preferred method of feminizing cannabis plants. This causes the plant to develop pollen sacs without compromising the lineages genes and here is how you can it in your own home:
- Choose two female plants that you will use. You need to make sure that each plant has strong genes. One of the plants will be chemically treated to grow male sex organs while the other will be pollinated.
- Purchase a colloidal silver solution that has a minimum of 30 parts per million (PPM) of silver. You can buy the colloidal silver solution in any store that sells dietary supplements.
- Spray the colloidal silver solution. You can directly apply the colloidal silver solution on the plant’s bud sites until they are drenched, you should do this each day of the first 3-4 weeks of the plant’s flowering stage.
You should stop spraying once you see the pollen sacs have appeared and beginning to open. Never smoke the buds that form on this plant because they may have been coated with colloidal silver.
- Collect the pollen. When you notice that the pollen sacs are swollen and begin to split open, this is a clear indication that the pollen sacs are ready to be harvested. You can harvest it by simply removing the pollen sacs from the plant and let them air dry for about a week and once it dries out, shake the sacs in a bag to gather the feminized pollen.
- Pollinate the second plant by using the pollen you have gathered. Take note that the female plant should have been in 2-3 weeks into its flowering stage for it to be pollinated.
- You can wait for about 6 weeks to harvest the seeds. Harvesting should be done once you notice that the calyxes on the pollinated plant are swollen and showing seeds.
Reason for Trying Feminized Seeds in Your Garden
Better Cannabis Genetics
A lot of cannabis strains that came from feminized cannabis seeds have had their genetics carefully controlled by a breeder. This is to ensure that it brings out defining characteristics of each strain. An advantage of this is that it gives consumers more options in terms of flavors, aromas, and cannabinoids.
These feminized plants are believed to be more productive, aromatic, powerful and attractive. The feminized seeds are also made to ensure that the plant being grown are working well in the conditions that a grower is growing on.
These feminized plants give a guarantee that no plant will be male or a hermaphrodite. When a female cannabis plant undergoes extreme stress, it can affect the results but using feminized seeds is a good way to increase yields, save work, and get higher value from the seeds.
Clone and Breed with More Control
When a breeder uses feminized plants for cloning, it gives them a greater likelihood that the plant is going to be a female plant. A noticeable advantage of using feminized seeds is the ability to better control the breeding of the plant.
It offers more control over the whole process and it seeks to standardize the cannabis industry. Also, it has helped by making the process of growing more reliable and for many reasons, it has become the standard in the cannabis industry.
Allows growers to work less with the Plants
If properly grown, a feminized cannabis plant can give a 100% guarantee that each plant grown from the seed will produce large amounts of bud. This will mean that a garden will yield more if they operate at or below plant count restriction.
